Actually early Christianity forbid charging usury (interest) so Christians wouldn't loan money. The jews didn't have that policy so they loaned and did the banking thing. The hatred of jews had more to do with paying off loans than the jews hand in killing Jesus
Jews killing Jesus is very debatable, as people say Jesus was a Jew, and a lot say the Roman's killed Jesus. But other than that you are morbidly correct
The reason why Jews are commonly stereotyped to love money is because 2,000 years ago, Christians leaders who hated Jews, put them into banking as back then, banking was a great sin, and they did not allow Jews to own farm lands. So if a person tries to stereotype a Jew about money, let them know its their fault for why Jews are associated to dealing with money.
